Zusammenfassung:A heat-shrinkable packaging article comprises a heat-shrinkable film tubing having an inside heat seal layer sealed to itself, with the heat seal layer having a thickness of at least 0.1 mil and made from a polymeric composition with a density < 0.92 g/cc, the seal layer comprising =2000 ppm antiblock particulates of average particle size =3µ fast-blooming release agent, slow- blooming release agent, and an outside layer. The packaging article can be dustless, and it passes a Standard Openability Test. Also disclosed is a dustless packaging article having a low peak or instantaneous coefficient of friction, an assembly comprising an imbricated set of packaging articles adhered to tapes, and a rotary chamber packaging process using the packaging articles. The packaging article can be dustless. Un artículo envasado termo-encogible comprende un tubo de película termo-encogible que tiene una capa interior de sellado térmico sellada así misma; la capa de termosellado teniendo un espesor de al menos 0.1 mil, y fabricada de una composición polimérica con una densidad
